both my motors have stainless allen head bolt kits from Snyder Motorsports -- Suspension Components For Your DRR ATV
think i paid like $18 + shipping
but i'd call them to order, i dont think they show up on the website, and they even did a paypal request for me to pay, as for the other bolts on our blasty's i just eventually replaced them all with stainless ones from ace hardware, prolly cost me more in the end, but allowed me to do a little at a time, ace hasnt failed me yet, even got a stainless/chrome swinger locking nut, only thing they didnt have was carrier bolts, but have the nuts
It all depends on what ya want and what ya want to pay. If you are doing the whole quad tho, the above kit is a good deal. There are some kits on ebay that talk about having 120+ fasteners but they aren't really full kits, just generic boxes of bolts and nuts.
